The Qb series are excellent for the price.
Chinese Air Rifles | Airguns | CO2-Powered | Archer Airguns
Depending if you want 12 gram (qb 78) or to use a bottle (qb 79) they are very upgradeable, with trigger kits,barrels,breechs,stocks,and etc. I shoot one myself and it is very nice. Lots of modding to be done to them as well, like drilling out the bolt,replacing the seal between the breech and bottom for a piece of rubber tube,spring work,valve work and etc.
I'd be happy to run you threw it if you want.
